The thing is, there's a minimum cost in making a quality power supply. You can buy cheap supposedly branded devices but why risk it? Seasonic produces a quality device that works exceptionally well, looks great and has all the right cable requirements for a PSU of this cost and power rating. Is it worth buying over the Corsair VX? Probably, the battlefield is littered with pros an cons, but essentially if you buy either you'd be making the right decision.
